GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 266,890, dated October31, 188

Application filed September 19,1882. (No model.)

To all whom it may concern:

Be it known that I, ELIAS B. REQUA, a citizen of the United States,residing at Jersey City, Hudson County, New Jersey, have invented newand useful Improvements in Gas- Burners, of which the following is aspecification.

The main objects of my invention are to induce strong upward currents ofair around the tips of two or more gas-burners which branch from acommon pipe, whereby the said currents shall be directed against thebase portions of the flames, so as to afford a free supply of oxygen tothe latter; also, to so arrange the burner-tips of a cluster of burnersthat the flames therefrom shall blend at their edges; and also to inducecurrents of air upwardly around the said tips, so as to feed the flames.To such end Isurround two or more gas-burners branching from a commonpipe with a perforated jacket, and connect the same at its upper openend with a concavo-convex perforated or impert'orate plate adapted tosupport a lamp chimney. The chamber or space within the jacket opensinto the concavity of the plate in which the burner-tips are located,and the burners, which are curved inwardly or made converging toward acommon central point, have the tips adapted to be turned so as to bringtheir slits into such relative position to each other that the flamesshall blend at their edges, as hereinafter described,and illustrated inthe drawings, in which- Figure 1 represents a side elevation of theburners, with thejacket, base-plate, and chimney in vertical section.Fig. 2 is a section taken at right angles to Fig. 1, the base-platebeing in this case made of an oval shape, as shown in Fig. 3, which is atop or plan view of said plate with two burners. Fig. dis a plan view ofa portion of the base-plate with three burners.

In Figs. 1. and 2 the plate is provided with round or substantiallyround perforations, while in the remaining figures it is provided withslits or slots.

In carrying out my invention I provideasection of gas-pipe, A, with twoor more curved branch pipes or burners, B, which are made toconvergeatiheirupperends. When twoburners only are employed they willhave a direct inclination toward each other, and when more than two ofsuch burners are used they willall haveadirect inclination towardacommoncentral point. capable of being turned thereon, whereby the respectiveslits of the tips can be brought into such relative position to eachother that the flames shallblend at their edges, and thus constitutepractically one light. blending being above the base of the flame, onlythe light-giving portions of the flames are united, so that the supplyof air to the base at each flame will be ample anda rapid consumption ofthe oxygen effected. These burners are inclosed by a slitted ortoraminous metal jacket,D, which is contracted at its lower end so as tolit closely around the pipe below the burners. This jacket connects atits upper end with a slitted or foramiuous concave-com vex plate,E, andconstitutes a support for the same. The slitted or foraminous plateconstitutes a base plate or support for the chimney F, and is providedwith an annular seatfor the chimney to rest upon, and also with aperipheral flange for holding the chimneyin place upon its seat. Athumb-screw, G, is also arranged to work through the flange of thebaseplate, so as to further secure the chimney.

' The tips of the burners are located within the concavity ofplate E,while the upper ends of the body portions of the burnersBcan eitherextend somewhat into said concavity or be on a line with or be slightlybelow the lowest portion of the said plate.

The jacket and the concavo-convex plate are connected together in anysuitable way, and a passage for the upwardly-induced currents of airformed between the two byyeason of the jacket being open at its upperend and connected with the base-plate, which has a cen tral openingcoinciding with the opening at the top of thejacket. The air, whichflows from all sides through the slits or perforations ot' the jacket,passes upwardly around the burners and their tips, and affords a freesupply of oxygen to the flames at their base. It will be evident thatthis inflow of air into and up through the jacket to the flames abovethe latter will be induced both by the upward draft through the chimney,caused by the rareiaction of the air therein, and also by therarefaction to a certain extent of the air which surrounds the burnerswithin the jacket.

The tips 0 of these burners are i The point of When the concavo-convexplate E is formed with slits or perforations an additional supply of airfor feeding the flames will be induced through the said openings in theplate. This plate can, however, be made imperforate, in which case theair-currents induced through the jacket will be stronger, and therebyafford a more rapid supply of oxygen to the base of the flames.

Figs. 3 and 4 illustrate the forms of openings in the plate E for theburners, one of which is adapted for two and the other for three of saidburners.

In conclusion, I will remark that two onefoot burners, with the aboveconstruction and arrangement of parts, will give as much light as theordinary six-foot gas-burner.

I am aware that gas-burners are well known which consist of two or moreburners emanating from apipe common to all; but such is not broadlyclaimed by me.

1 am also aware that foraminous air-distributers and air-currentregulators have long been usedin various ways in connection with lampburners; but such does not constitute my in- Vention. i

What I claim isl. The combination, with a series of gasburners emanatingfrom a common source of gas-supply and arranged in the relative positiondescribed, of aperforated jacket surrounding the burners and having anopen upper end through and above which the burner-tips project, and abase'plate projecting laterally from the upper edges of the open end ofthe jacket and provided with means for supporting a chimney,substantially as and for the purpose described.

2. The combination, with a series of gasburners emanating from a commonsource of 40 gas-supply and arranged in the relative position described,of aperforatedjacketsurrounding the burners and having an open upperendthrough and above which the burner-tips project, and a concavo-con vexperforated baseplate secured around the open upper end of the jacket andshielding the burner-tips, said baseplate having means to support achimney, substantially as described.

3. The combination, with two or more gasburners branching from a mainpipe, of the perforated jacket surrounding said burners and fitted atits lower contracted end to the pipe below the burners, and theconcavo-convex plate for supporting the lamp-chimney, provided with acentral opening and secured to and supported by thejacket, which is openat its top, so as to allow the air which flows in through its sides topass upwardly around the burners to the base of the flames, the tips ofthese burners being located within the concavity of the base-plate abovethejacket, and being adapted to direct the flames toward each other,substantially in the manner and for the purpose described.

In testimony whereofl have hereunto set my hand in the presence of twosubscribing witnesses.
